The Chex Quest series of games (Chex Quest, Chex Quest 2 and Chex Quest 3) has been developed and released in 1996 by Digital Café. Based on the DOOM engine, this game franchise was a non-violent variant of DOOM made as an advertisement program targeting children from 6 to 9, bundled in the Chex breakfast cereal packs to promote the product. The main character of these games being a piece of Chex cereal, who must fight an invasion of slimy green creatures, the Flemoids.

NightFright, member of the Doomworld forums, recorded all the music tracks from the 3 Chex Quest games with Arachno SoundFont, BASSMIDI Driver and the AIMP audio player/converter.

The pack is available in two variants: a high-quality version aimed at being played on any audio device, and an other version optimized to be used as a replacement soundtrack in the original game, with all files organized and named to be added directly on any DOOM port supporting music packs in ZDoom's format, such as ZDoom itself, GZDoom or Skulltag.
